Preparation

Bring a large pot of salted water to a boil over high heat. Cook pasta as directed on the package.

While the pasta is cooking, heat 1 tablespoon of olive oil in a medium skillet over medium-high heat. Add onion and garlic, reduce to medium and cook until the onions are softened and translucent. Stir occasionally.

Place the cooked onion and garlic, drained red peppers, half-and-half and red pepper flakes in a food processor or blender and purée until smooth.

Return sauce to pan and heat through over moderate heat for about 10 minutes.

Drain the pasta, then return it to the pan and pour sauce over the top. Stir to coat the pasta with sauce. Serve with torn basil leaves and Parmesan cheese
